I believe SNMP is a binary protocol, so a simple send/expect may not
work.
You could probably use check_snmp and check for a variable that is used
pretty much everywhere; I use system.sysUpTime.0 (the numeric OID is
1.3.6.1.2.1.1.3.0) in a few places. Something like:
define command {
command_name check_snmp
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -w $ARG2$ -c $ARG3$ -o $ARG4$
}
define service {
service_description SNMP uptime
check_command check_snmp!community!1:!1:!1.3.6.1.2.1.1.3.0
...
}

I don't speak for anybody but myself - that's enough trouble.
